I always looked to avoid the uphill, or leave it for the last 5 min walk. But the last couple of times I have followed a route which has a slight downhill grade on the second half, and found it harder than the level. The energy used was a little less, probably because of downhill momentum but the impact on my joints was greater.
How does everyone else find it? Which do you prefer?
I tended to clench my toes when running down hill once i realised this and relaxed my feet it wasnt too demanding on the joints.
Ooohhhh these hills are the bain of my life! Downs are hard on my knees easy on the lungs. Ups are just plain hard all over 
I'm working on one of the steepest hills in Aberdeen just now, oh I know I'm a masochist 
Its called Jacobs Ladder, perhaps I should rename it stairway to H (hot place). But you know if you want to go on and do 5K/10K runs you have to be able to get up the ups and safely down the downs.
How do you record your runs? Not which app, but when do you press 'start'?
Which app do you use when running to track your runs?
At what point do you start finding the longer runs more enjoyable?
Does it count if you run downhill?
Which week challenged you?
